Make the decisions in the right order

Decide framing and delivery resolution first. Next decide the timeline’s motion cadence. Only then compare codec and bitrate. Otherwise, a larger file may simply contain duplicated frames or an enlarged low-resolution image.

For example, a 1080 × 1920 export contains 2,073,600 pixels per frame. A 2160 × 3840 export contains four times as many. That arithmetic does not mean it contains four times as much captured detail: the source, crop and processing determine what those pixels represent.

Separate file compatibility from picture quality

MP4 and MOV describe containers. H.264 and HEVC describe video codecs. A filename ending in .mp4 does not tell you which codec is inside, and renaming a MOV file does not convert it to H.264.

A compatible codec helps a player decode the file. It does not set the camera focus, undo denoising or determine whether a previous export was compressed too heavily. Keep those questions separate when troubleshooting.

Choose frame rate deliberately

Keep an ordinary 30 fps project at its intended cadence unless you have a reason to convert it. Exporting a 30 fps source at 60 may repeat frames or invoke an interpolation feature; those outcomes are different from filming 60 distinct moments each second.

Fractional rates matter too. A measured 29.97 or 59.94 is not automatically a fault. For variable-frame-rate footage, average fps does not describe every frame interval. If motion is uneven, inspect actual playback and the timeline instead of correcting the number in a filename.

Estimate size before making a huge export

For a constant illustrative video rate, approximate decimal megabytes as megabits per second × seconds ÷ 8. At 10 Mbps, 30 seconds is about 37.5 MB of video payload. At 20 Mbps it is about 75 MB. Audio and container overhead are extra; variable-rate files will not follow a fixed target exactly.

Use a difficult scene for a local A/B comparison. Hold resolution, frame rate and codec constant while changing the encoder’s quality setting. Look at moving textures and dark gradients as well as the file size. More data can help a stressed encode, but cannot restore an already damaged source.

Read the destination’s limits separately

Fulres’s input limit is 2 GB for an MP4 or MOV. Passing that check means the file is small enough to attempt preparation; it does not mean every posting destination will accept all of its properties. TikTok’s API and the connected account can impose additional restrictions.

Check the actual account options before direct publishing. A source above the posting API’s supported frame-rate range may require a deliberate delivery export even though preserving the original source remains useful. Fulres does not silently turn a high-frame-rate file into an API-compliant one.

Review the actual output

Save a clearly named export and play it locally. Then prepare that same file in Fulres and read its inspected dimensions, frame rate and audio information. Keep the source project so an export decision can be changed without using a compressed delivery file as the master.

• ✓Framing and text survive the intended crop.
• ✓Motion is smooth at the chosen timeline cadence.
• ✓Local audio is present and synchronized.
• ✓Color is reviewed in a compatible player.
• ✓The file meets the input limit and the chosen posting path’s restrictions.
