Rendering options without losing video quality

Hi everybody,

I'm Jacopo and this is the first time I'm posting here.

I've been using Vegas for the last 2 years and I'm loving the program, but I've always had some problems with the rendering options.

Lately, I'm noticing a huge loss of quality/smoothness between the original video footage from my camera (a Sony Handycam HDR-CX550) and the final rendering after editing the video with Vegas. I've tried several rendering options, the original pre-edit video is just better, and "smoother". It seems I'm losing FPS even if the frame rate is the same.

Original camera video is a .MTS file, 1440x1080, 8669kbps, 29.97 FPS

Do you have any suggestions for good rendering settings?

Thank you very much!

Hi Jacopo,

Can you post a screenshot of your Project Properties and the Render format Template you are using. Your source media I think in interlaced, so maybe there is just a setting to change and make an improvement.

Also, what version and build of Vegas Pro are you using?

Strange, your Cam is an AVCHD camera with 1080i (1920x1080) recording possibility, why recording in a lower resolution and giving quality already away while recording?

There are enough templates to preserve this quality, chosing the right one depends one your goal.

@Eagle Six. Here's the Project Proprieties. As for the Render format, I've tried several with basically the same results, the one I use the most is Internet 1920*1080-30p (Video: 29,970 fps; 1920x1080 Progressive; YUV; 16 Mbps Pixel Aspect Ratio: 1,000). That's because in the same project there's also footage from a GoPro 7 (1920*1080 at 30 fps)

I'm using Vegas Pro 16.0 build 424.

@3POINT: I just noticed I can record in HD FX, thank you so much for the info!

Are you sure your video files are 1440x1080?? the specs for that camera says 1920x1080.

Sometimes its a good idea to supply us with a little sample project and footage. Just record anything where you can reproduce the problem. Upload it to dropbox or somewhere and share it with us. We can then take a look and even render it out and see what results we all get.

The only way I see to get a little better quality, because you're combining/rendering 1080p with 1080i to 1080p, is to set in the project settings the deinterlace method to "smart adaptive".

Your original video is 30i (interlaced) so there are "60 movements per second". While rendering to 30p you are reducing it to "30 movements per second". 30p will never ever be as smooth as 30i. If you need smoothness, you need to bob-deinterlace to 60p (not sure if it is possible to do in Vegas). However, in this case you will also need to increase bitrate.

I'd like to thank you all for your responses.

I've changed the deinterlace method to smart adaptive and rendered the video in 60p instead of 30p or 60i and now the final video has its original crispness/smoothness.

Thanks again guys.

You know, it's a toss up. Two methods produce two outcomes that may or not be obvious, depending on source, motion complexity, viewing conditions, and user experience,

30i (59.97i) -> 30p

With adaptive field smoothing produces true 30p, retaining the most source data. Limited to 30fps.

30I ->60p (Bob)

Uses alternate fields plus interpolation to create frames that are about 50% data, 50% interpolation. Smoothest playback, but less accurate. Introduces additional shadow noise.
