image sequences vegas
Is it better to render/import image sequences (as for example mp4 clips) to project timeline or just import the sequence itself and let vegas render them with the whole project? I don’t understand what’s happening under the hood but advice appreciated!

Previewing an image sequence can be pretty heavy work depending on the source image sizes, so rendering them out to a video makes sense for smooth editing – use an intermediate format or low compression (high bitrate) to maintain quality.
If you need to do any pan/crop or major colour/exposure etc adjustments to the image sequence, do them before rendering to get the best quality output.

Thanks Matt. I’m not worried about the quality of the preview as much as the final render quality of the entire project. Does adding a mp4 clip to the timeline alongside other captured HDV video (mostly m2t files I think??)cause degradation of the re-rendered mp4?

Yes, absolutely. Image sequences are by definition intra-frame compressed, meaning that the final render will have less overall compression artifacting. If final image quality is your top priority, stick with image sequences.

If you get reasonably smooth preview of your project with the image sequence then just stick with that.
If the preview is really slow, then make whatever major adjustments you need (mainly pan/crop) on the image sequence, then render that to a high-quality format (preferably lossless, or Cineform or similar) at your desired project resolution, then replace the image sequence with the rendered segment and continue editing.

Thanks Matt and Seth! Will stick to image sequences….
