vegas pro 22 stuck rendering dvd

Yesterday, I was experiencing big slow-downs/stalling when rendering to MAGIX AVC/AAC MP4 - both UHD and HD - when rendering in VP22b250. With a bit of experimentation, I found that changing the 'Deinterlace method' in Project Properties to 'Smart Adaptive (GPU only)' solved the problem and rendering then went smoothly without any stalling/freezing. The HD render of the 96 mins long project was at 11 fps and an UHD render of the same project was 10.2 fps.

I will try that tomorrow! Will it work with an already finished project?

”… rendering video to burn dvd.“

DVDs are MPEG-2. Use the Mainconcept MPEG-2 template for DVD. Blu-ray can be either MPEG-2 or AVC.

Something doesn't match up. Is your project 720x480 or 640x480? What size is your source material and what is its PAR?

None of the frame rates match the chosen aspect ratios in the 3 pics either.

Shown Project settings are not from actual DVDproject as shown in UI screenshot. (See also comment of @EricLNZ) Project is 720x480 29,970i NTSC 4:3

@Ken-Tonks Why did you create for every event an extra audiotrack?

When burning a DVD directly from timeline, Vegas uses the correct rendertemplate (from correct project settings) and format as shown in your screenshot: Don't get confused by "60i" which is the same as i29.970. Vegas will first render an DVD-image that will be used afterwards to burn the actual DVD. Make sure that your HD has enough space (at least 2 times size of project) for this image. Also make sure that image also fits on DVD.

For checking a possible render issue; first render your project with following rendertemplate:

IT WORKED!

Thank you so much! Going to fire up stereo and see if it plays and looks good but I don't expect a problem. Amazing. Do you know why this works?

I'm not sure to be honest. My guess is they are often different sizes as they are music video MP4's. Sometimes I have to stretch/crop a video to fit the frame. Some are old and sized for square T.V.'s and newer ones are often landscape for newer flatscreens. Vegas seems to pick its own size from one of the videos in the project, but all the source videos don't always match.

thanks for you help again. I don't know that I created a new event for every audio track. Maybe, not sure what you mean. These are MP4 music videos that all have their own audio. Some are clear and bright and others are dull and need boosting in dynamics, or distortion or just track EQ. But each audio track is adjusted for more punch and brilliance separately. Is that what you were referring to?

rendered flawlessly with your adjustment! Thanks! Just fired up stereo and it played back great. thanks so much.

Do you mean the "new project" settings? It was my understanding that VEGAS selects the custom setting automatically when you add your first media file to the timeline. If I'm wrong what do I need to change it to? thanks!

Pick a Pixel Aspect Ratio and Frame Rate that's part of the DVD spec. per Wikipedia:

https://en.wikipedia.org/wiki/DVD-Video

Video data

To record digital video, DVD-Video uses either H.262/MPEG-2 Part 2 compression at up to 9.8 Mbit/s (9,800 kbit/s) or MPEG-1 Part 2 compression at up to 1.856 Mbit/s (1,856 kbit/s). DVD-Video supports video with a bit depth of 8 bits per color, encoded as YCbCr with 4:2:0 chroma subsampling.[12][13]

The following formats are allowed for H.262/MPEG-2 Part 2 video:[14]

At a display rate of 25 frames per second, interlaced or progressive scan (commonly used in regions with 50 Hz image scanning frequency, compatible with analog 625-line PAL/SECAM):

720 × 576 pixels (D-1 resolution, 4:3 fullscreen or 16:9 widescreen aspect ratio)

704 × 576 pixels (4CIF resolution, 4:3)

352 × 576 pixels (China Video Disc resolution, 4:3)

352 × 288 pixels (CIF resolution, 4:3)

At a display rate of 29.97 frames per second, interlaced or progressive scan (commonly used in regions with 60 Hz image scanning frequency, compatible with analog 525-line NTSC):

720 × 480 pixels (D-1 resolution, 4:3 or 16:9)

704 × 480 pixels (4SIF resolution, 4:3)

352 × 480 pixels (China Video Disc resolution, 4:3)

352 × 240 pixels (SIF resolution, 4:3)

The following formats are allowed for MPEG-1 video:

352 × 288 pixels at 25 frame/s, progressive (CIF/VCD resolution, 4:3)

352 × 240 pixels at 29.97 frame/s, progressive (SIF/VCD resolution, 4:3)

The MPEG-1 Part 2 format does not support interlaced video. The H.262/MPEG-2 Part 2 format supports both interlaced and progressive-scan content, and can handle different frame rates from the ones mentioned above by using pulldown. This is most commonly used to encode 23.976 frame/s content for playback at 29.97 frame/s. Pulldown can be implemented directly while the disc is mastered, by actually encoding the data on the disc at 29.97 frames/s; however, this practice is uncommon for most commercial film releases, which provide content optimized for display on progressive-scan television sets.[citation needed]

Alternatively, the content can be encoded on the disc itself at one of several alternative frame rates, and use flags that identify scanning type, field order and field repeating pattern. Such flags can be added in video stream by the H.262/MPEG-2 Part 2 encoder.[15][16] A DVD player uses these flags to convert progressive content into interlaced video in real time during playback, producing a signal suitable for interlaced TV sets. These flags also allow reproducing progressive content at their original, non-interlaced format when used with compatible DVD players and progressive-scan television sets.[17][18]

Audio data

The audio data on a DVD movie can be Dolby Digital (AC-3), DTS, PCM, or MPEG-1 Audio Layer II (MP2) format. In countries using the PAL system standard DVD-Video releases must contain at least one audio track using the PCM, MP2, or AC-3 format, and all standard PAL players must support all three of these formats. A similar standard exists in countries using the NTSC system, though with no requirement mandating the use of or support for the MP2 format. DTS audio is optional for all players, as DTS was not part of the initial draft standard and was added later; thus, many early players are unable to play DTS audio tracks. Only PCM and DTS support 96 kHz sampling rate. Because PCM, being uncompressed, requires a lot of bandwidth and DTS is not universally supported by players, AC-3 is the most common digital audio format for DVDs, and 96 kHz is rare on a DVD. The official allowed formats for the audio tracks on a DVD-Video are:

PCM: 48 kHz or 96 kHz sampling rate, 16 bit or 24 bit Linear PCM, 2 to 6 channels, up to 6,144 kbit/s; N. B. 16-bit 48 kHz 8 channel PCM is allowed by the DVD-Video specification but is not well-supported by authoring applications or players;

AC-3: 48 kHz sampling rate, 1 to 5.1 (6) channels, up to 448 kbit/s;

DTS: 48 kHz or 96 kHz sampling rate; channel layouts = 2.0, 2.1, 5.0, 5.1, 6.1; bitrates for 2.0 and 2.1 = 377.25 and 503.25 kbit/s, bitrates for 5.x and 6.1 = 754.5 and 1509.75 kbit/s;[19]

MP2: 48 kHz sampling rate, 1 to 7.1 channels, up to 912 kbit/s.

DVDs can contain more than one channel of audio to go together with the video content, supporting a maximum of eight simultaneous audio tracks per video. This is most commonly used for different audio formats—DTS 5.1, AC-3 2.0 etc.—as well as for commentary and audio tracks in different languages.

Data rate

DVD-Video discs have a raw bitrate of 11.08 Mbit/s, with a 1.0 Mbit/s overhead, leaving a payload bitrate of 10.08 Mbit/s. Of this, up to 3.36 Mbit/s can be used for subtitles, a maximum of 10.08 Mbit/s can be split amongst audio and video, and a maximum of 9.80 Mbit/s can be used for video alone.[20] In the case of multiple angles the data is stored interleaved, and so there is a bitrate penalty leading to a max bitrate of 8 Mbit/s per angle to compensate for additional seek time. This limit is not cumulative, so each additional angle can still have up to 8 Mbit/s of bitrate available.

Professionally encoded videos average a bitrate of 4–5 Mbit/s with a maximum of 7–8 Mbit/s in high-action scenes. Encoding at less than the max bitrate (like this) is typically done to allow greater compatibility among players,[21] and to help prevent buffer underruns in the case of dirty or scratched discs.

In October 2001, aiming to improve picture quality over standard editions, Columbia TriStar Home Entertainment offered "Superbit"—a premium line of DVD-Video titles having average bitrates closer to 6 Mbit/s. Audio quality was also improved by the mandatory inclusion of both Dolby Digital and DTS 5.1 surround audio tracks. Multiple languages, angles, and extra audio tracks were eliminated to free up more space for the main title and thereby to ensure the highest data rate possible. In January 2007 the Superbit line was discontinued.
