Video Codecs, Formats, Log, and RAW Explained

The confusing part is that camera menus mix different ideas in one place. You may see MOV · H.265 · 10-bit · 4:2:2 · F-Log2 · 200 Mbps, and it looks like one huge format. It is not. It is six separate choices stacked together.

Once you separate those layers, the menu becomes much calmer. You choose a file box, a compression method, a color profile, and a quality level. Then you decide whether your computer, cards, and editing plan can handle it.

If you are still learning exposure, start with the exposure triangle. If you are choosing a camera for video, pair this with best cameras for video and best vlogging cameras.

The stack, in order

Pick a recipe below and watch the menu string come apart. Each token is a separate choice, color-keyed to the layer it controls. Tap any token to see what it does.

The container is the least interesting part. MP4 and MOV are boxes. A MOV file can contain H.264, H.265, ProRes, or other codecs. An MP4 file can also contain different codecs. Do not buy a camera because it says MOV; look at what is inside.

The codec matters more. It decides how the camera shrinks raw video data into a file you can store. H.264 is older and easy to play. H.265 is smaller for similar quality but harder to edit. ProRes is bigger but easier for editing. RAW keeps the most control, but creates large files and adds work.

Codec decoder ring

Codec or format	Plain-English meaning	Use it when	Avoid it when
H.264	The universal video codec	You want easy playback, small files, fast delivery	You plan to push color hard
H.265 / HEVC	More efficient compression than H.264	You want better quality per file size, especially in 4K	Your computer struggles with playback
AV1	Newer efficient codec used heavily online	You are exporting for platforms or devices that support it	Your camera or editor does not support it well
ProRes 422	Large, edit-friendly production codec	You want smooth editing and strong color files	Card space and storage are tight
ProRes RAW	RAW-style video wrapped for compatible editors	You need RAW control in an Apple-friendly pipeline	You edit in software that does not support it cleanly
Blackmagic RAW	Blackmagic's compressed RAW video format	You use Blackmagic cameras or Resolve and want RAW control	You need tiny files or universal playback
Proxy	A small temporary editing file	Your computer cannot play the originals smoothly	You think it replaces the original footage

For most creators, the practical choice is simple: shoot 10-bit H.265 if your camera and computer can handle it, or H.264 if you need maximum compatibility. Use ProRes when editing speed matters more than file size. Use RAW when the grade, VFX, or production pipeline truly needs it.

Bit depth: 8-bit versus 10-bit

Bit depth controls how many steps of tone and color the file can store.

An 8-bit file has 256 values per channel. That is fine for standard color and light edits. Push it hard, especially with a flat Log profile, and you can see banding in skies, walls, and gradients.

A 10-bit file has 1,024 values per channel. That gives a lot more room for Log, color correction, and smooth gradients. If you want to shoot D-Log M, F-Log2, S-Log3, C-Log, V-Log, or any similar flat profile, 10-bit is the normal floor.

Twelve-bit and higher show up in RAW and higher-end formats. More bits are useful when the footage will be graded heavily, keyed, composited, or matched across cameras. They also demand more storage and a cleaner workflow.

Chroma subsampling: 4:2:0 versus 4:2:2

Human eyes notice brightness detail more than color detail, so many codecs save space by recording less color resolution than brightness resolution. That is chroma subsampling.

4:2:0 is common in consumer and web files. It is efficient and usually fine for normal shooting. 4:2:2 keeps more color detail, which helps with grading, green screen, product color, skin tones, and any footage that will be pushed. 4:4:4 keeps full color resolution, but it is mostly a high-end post-production format.

If you are choosing between two similar modes, 10-bit 4:2:2 is the stronger editing file. 8-bit 4:2:0 is the easier and smaller delivery-style file.

Log is not a codec

Log is a color and tone profile. It records a flatter image so highlights and shadows fit into the file with less clipping. It looks washed out on purpose. You are supposed to correct it in editing.

Standard color, often Rec.709, tries to look finished straight out of camera. Log tries to preserve editing headroom. HLG is a different idea: it is an HDR profile for displays and delivery systems that support HDR.

This is the important split:

• Codec: how the file is compressed.
• Log profile: how brightness and color are mapped before compression.
• LUT: a conversion look that turns Log into normal contrast and color.

You can have H.265 in standard color. You can have H.265 in D-Log M. You can have ProRes in F-Log2. The codec and the profile are separate choices.

The brand names

Camera brands name their Log curves differently. The names are annoying, but the logic is consistent.

Brand	Common names	What to know
DJI	D-Log M, D-Log, D-Log2	D-Log M is the easier mid-flat profile on many creator cameras. D-Log and D-Log2 are deeper profiles on more advanced models.
Fujifilm	F-Log, F-Log2	F-Log2 is flatter and holds more dynamic range than F-Log, but it needs more careful exposure and grading.
Sony	S-Log2, S-Log3, S-Cinetone	S-Log3 is the common serious grading profile. S-Cinetone is a more finished look with less grading work.
Canon	Canon Log, C-Log2, C-Log3	C-Log3 is usually the easier all-round Log choice. C-Log2 is flatter and aimed at maximum range on capable bodies.
Panasonic	V-Log, V-Log L	Panasonic's Log profiles are common in hybrid and cinema bodies. V-Log L is a lighter version for smaller sensors and older bodies.
Nikon	N-Log	Nikon's flat profile for grading, often used with external recorders on some bodies.
Blackmagic	Film / Gen 5 Film	Blackmagic's flat color science used with Blackmagic RAW and DaVinci Resolve.

Do not choose the flattest profile because it sounds professional. Choose the profile that matches your file and your plan. A 10-bit file with a mild Log profile is often better for a solo creator than a very flat profile exposed badly.

What D-Log M means

D-Log M is DJI's creator-friendly Log profile. It is flatter than normal color and gives more room to adjust highlights, shadows, and saturation, but it is not as flat as a full cinema Log curve. That is the point. It gives travel, drone, action, and pocket-camera shooters more grading room without making every clip miserable to correct.

Use D-Log M when:

• The camera records it in 10-bit.
• You will apply a proper conversion LUT or correct the footage manually.
• The scene has bright sky, white walls, windows, snow, water, or hard sun.
• You want to match clips from several cameras.

Skip D-Log M when:

• You need fast files straight from the camera.
• You are shooting in very low light and do not want extra noise showing up in the grade.
• You do not want to color correct.

The same basic rule applies to F-Log2, S-Log3, C-Log3, V-Log, and N-Log. Log protects the file for editing. It does not make the image better automatically.

RAW video is not the same as photo RAW

Photo RAW is one still frame of sensor data. Video RAW is a stream of frames, usually compressed in a format like Blackmagic RAW, ProRes RAW, REDCODE RAW, or another brand-specific system.

The benefit is control. Depending on the format and software, RAW video can let you adjust white balance, ISO interpretation, highlight recovery, debayering, and color science with more freedom than a normal compressed file. It is useful for high-end color work, VFX, and productions where the image will be pushed hard.

The cost is everything around it: larger files, faster cards or SSDs, more drive space, heavier backups, and a computer that can play the files. RAW is a production choice, not a default quality button.

For most YouTube, travel, vlog, and small-business work, 10-bit Log is the practical ceiling. RAW is there when the job actually needs it.

All-Intra versus Long GOP

Some cameras let you choose All-Intra or Long GOP.

Long GOP compresses groups of frames together. It gives smaller files, but the computer has to work harder to reconstruct each frame during editing. All-Intra compresses each frame more independently. Files are much bigger, but editing can feel smoother and individual frames are easier for the software to handle.

If storage is tight, use Long GOP. If your camera, cards, and storage can handle it, and editing smoothness matters, All-Intra is nicer to work with.

What to choose in real life

Here is the practical menu answer.

Situation	Sensible choice
Fast social clips	H.264 or H.265, standard color, 8-bit or 10-bit
Beginner vlogging	Standard color, 4K 24p or 30p, good audio
Travel with grading	10-bit H.265, D-Log M or similar mild Log
YouTube talking-head work	10-bit H.265 or H.264, standard color or mild Log
Paid video with color correction	10-bit 4:2:2 Log, ProRes if file size is acceptable
Green screen or product color	10-bit 4:2:2, controlled light, careful white balance
Narrative or heavy grade	ProRes, RAW, or a high-bitrate 10-bit Log mode
Slow computer	H.264, standard color, or use proxies

If you do not know what to pick, choose 4K 24p or 30p, 10-bit if available, normal color if you do not edit, and Log only when you are ready to correct it. Get clean exposure and sound first. The codec cannot rescue sloppy capture.

Storage and card math

Bitrate tells you how fast storage fills. Divide megabits per second by 8 to get megabytes per second.

So a 200 Mbps mode writes about 25 MB/s. Ten minutes at that rate is roughly 15 GB before overhead. A 400 Mbps mode doubles that. ProRes and RAW can climb much higher.

That is why memory cards and portable SSDs are not boring accessories for video. A card that is fine for stills may fail on a high-bitrate video mode. Look for the sustained write rating, not the biggest number on the label.

Common mistakes

The first mistake is shooting Log in 8-bit because the menu allows it. The file may look fancy, but it can break apart when corrected. If you want Log, choose 10-bit when the camera offers it.

The second mistake is using Log for every scene. In controlled light, standard color can be cleaner and faster. In low light, a flat profile can make noise more visible once you lift contrast.

The third mistake is confusing a delivery codec with a capture codec. H.264 is excellent for sharing. ProRes is excellent for editing. RAW is excellent for control. Those are different jobs.

The fourth mistake is ignoring the edit computer. H.265 can be compact and beautiful but still feel awful on an older laptop. Proxies are not cheating; they are normal.

The fifth mistake is buying a camera for a codec without budgeting for the cards, drives, backups, and time that codec demands.

The sane default

For most people, the best default is:

• 4K 24p or 30p.
• 10-bit if available.
• H.265 if your computer handles it, H.264 if compatibility matters more.
• Standard color if you want fast turnaround.
• Mild Log, such as D-Log M or C-Log3, only if you will color correct.
• ProRes or RAW only when the project justifies the storage.

That setup gives you clean files without turning every shoot into a data-management problem.

Is D-Log M the same as RAW?

No. D-Log M is a flat color profile recorded into a compressed video file. RAW video records a more sensor-level data stream with far more post-production control. D-Log M is easier and smaller; RAW is heavier and more flexible.

Should I use H.264 or H.265?

Use H.264 when compatibility and easy playback matter most. Use H.265 when you want better quality for the file size and your camera, computer, and editor handle it cleanly. If H.265 playback stutters, use proxies or switch to H.264.

Is F-Log2 better than F-Log?

F-Log2 is flatter and designed to hold more dynamic range, so it can be better for heavy grading on capable Fujifilm bodies. It also needs more careful exposure and a proper correction. F-Log is easier when you want a simpler grade.

What is 10-bit 4:2:2 and why does everyone mention it?

It means the file keeps more tone and color information than 8-bit 4:2:0. That extra data helps with Log correction, skin tones, green screen, and heavy color edits. It is not required for casual clips, but it is a strong target for serious video.

Do I need ProRes or RAW for YouTube?

Usually no. YouTube delivery compresses everything again, so ProRes and RAW matter mainly because they make editing and grading stronger before export. For most YouTube work, a clean 10-bit H.265 or H.264 file is enough.
