Post-production guide
Video delivery: editing, review, and formats
Ask GLMedia about video editing and post-production. We can review source material, versions, and formats to plan delivery.
Define the delivery and review process
Tell us what you want to communicate and which material is available. With the deadline and intended destination, we can review scope and prepare a post-production proposal before the script is final.
Start by defining what each recipient needs: an edited piece, a review version, a master, or a project with its media. These files serve different purposes and should be identified before export.
We can help organize material, message, and review while decisions are still open. DaVinci Resolve is a documented example here; formats and features require checks in the selected tool and version.
Media, workstation, and delivery
- Media
- Prepare originals and working copies in identifiable folders. Record which files are on local disks and which use shared storage.
- Workstation
- Record operating system, GPU, software version, and required plug-ins. The official codec table separates conditions by platform and edition.
- Delivery
- Define destination, aspect ratio, resolution, frame rate, audio, and subtitles. Separate the review file from the requested master.
What to prepare
Share the video’s purpose, available media, approximate duration, and date. We can help organize an initial selection before all elements are ready.
Gather text, names, logos, and credits for inclusion. Agree on who reviews editing, factual details, and sound, and how versions will be identified.
Confirm container, codec, resolution, frame rate, aspect ratio, audio, and captions with the recipient. A lightweight review file does not automatically replace a master or an editable project with media.
Basic preparation
- Record Resolve edition and version before opening a copy of an existing project. Preserve the previous working state.
- Test representative clips from each camera and recorder. Record format, codec, audio, and location as well as file extension.
- Check that the project can find media. If using proxies, verify links to originals before delivery too.
- Agree on project and final file formats with the recipient. Prepare a picture, text, sound, and subtitle sample where applicable.
- Save the project and prepare media backup. Test that the planned recovery or transfer copy opens and finds its files.
- Agree on a reviewer or review process. Identify each version and collect comments with time reference, requested change, and priority, so picture, text, names, sound, and captions are reviewed against the same file.
- Export a sample and inspect it outside the timeline. Check start, end, duration, content, and audio before producing the complete file.
Three technical questions
What should I check when Media Offline appears?
Check that the disk or folder exists and is accessible, and identify missing clips. If location changed, the manual describes relinking options in the Media Pool.
Work on a copy and check clip correspondence before accepting changes. An offline display alone does not establish that the original is lost.
Do I need Studio because a file will not open?
First identify codec, profile, operating system, version, and edition. Check the exact combination against the official format list; camera name or extension is insufficient.
Separate import, playback, and delivery format. We can review a sample before choosing conversion or additional tools.
Is a completed render ready for delivery?
Inspect the generated file in the destination player or system. Compare picture, sound, text, and duration against the approved version.
For an error, note its location and whether it also appears in the timeline. Preserve the previous version while preparing and checking a correction.
Checks by symptom
| Symptom | Check | What it helps distinguish |
|---|---|---|
| Media Offline | Location and access for affected clips. | Media path or link. |
| Unrecognized file | Codec, profile, platform, and edition. | Combination compatibility. |
| Incorrect delivery | Final file against timeline and review. | Editing or export. |
Limits and precautions
Preserve originals and recoverable copies before updating or reorganizing folders. Verify backup contents before removing another copy.
Test version, plug-in, or format changes on a representative copy outside active work. Preserve results and a way to resume the previous state.
Agree on credits, sources, and authorized material before final approval. Technical and editorial reviews must refer to the same final version.
