HDV to SD-DVD using MPEG Streamclip, an obeservation
There are lots of threads on this subject and almost all of them suggest using compressor.
I have used the compressor and was quite satisfied with the final dvd output, but still there were some problems.1.Shots with a lot of movements look very bad. I guess it’s because of interlacing and field order issue.
2.The comperessor takes a lot of time to produce the output.This is what I did for my last project which was shot in HDV.
1. Captured and edited in ProRes 1440*1080
2. Exported quicktime movie from FCP
3. Converted the quicktime movie to DV using MPEG Streamclip.
4. Burned a DVD using the DV file.I was satisfied with the quality of the dvd, in fact the problem
#1 that I faced using compressor was totally absent. The time taken for this whole process was nothing compared to compressor.Now my doubt is that am I doing something wrong here?
Because it sounds so simple but then why haven’t I read/heard it somewhere else? -

Because it sounds so simple but then why haven’t I read/heard it somewhere else?”Yes, sorry to say, but you’re doing plenty wrong Pradip. Not only are you hitting your HD video with an extra compression step, you’re hitting it with an extra step of DV compression, which is about as bad as it gets.
Your HD video is recorded in beautiful 4:2:2 color space, then you’re hitting it with DV compression, which not only compresses it at a 5:1 ratio, but chucks out enormous amounts of color information, knocking it down into 4:1:1 color space. Then, on top of that, you’re then encoding it to MPEG2 for the DVD, which compresses it yet again, big time.
Do you have any text and/or graphics in this video? I’m guessing you must not, because if so, the edges should look like they’ve been eroded with acid.

HDV is 4:2:0…
But yeah, the workflow is really wrong. I’ll post the quick and dirty workflow that was written by David himself.
#42 – Quick and dirty way to author a DVD
Shane’s Stock Answer #42 – David Roth Weiss’ Secret Quick and Dirty Way to Author a DVD:
The absolute simplest way to make a DVD using FCP and DVDSP is as follows:
1. Export a QT movie, either a reference file or self contained using current settings.
2. Open DVDSP, select the “graphical” tab and you will see two little monitors, one blue, one green.
3. Select the left blue one and hit delete.
4. Now, select the green one, right click on it amd select the top option “first play”.
5. Now drag your QT from the broswer and drop it on top of the green monitor.
6. Now, for a DVD from an HD source, look to the right side and select the “general tab” in the track editor, and see the Display Mode, and select “16:9 pan-scan.”
7. Hit the little black and yellow burn icon at the top of the page and put a a DVD in when prompted. DVDSP will encode and burn your new DVD.
THATS ALL!!!
NOW…if you want a GOOD LOOKING DVD, instead of taking your REF movie into DVD SP, instead take it into Compressor and choose the BEST QUALITY ENCODE (2 pass VBR) that matches your show timing. Then take THAT result into DVD SP and follow the rest of the steps. Except you can choose “16:9 LETTERBOX” instead of PAN & SCAN if you want to see the entire image.

Had you chosen letterbox in dvdsp you’d get the same result there. DVDSP does a decent encoding job and if I remember right you can choose 2 pass vbr. Having worked on a series of DVDs that had to go through numerous approvals, it was certainly easier to output a daily qt reference, overwriting the previous reference, opening up DVDSP and just hitting burn. For the final, I did the compressor pass and replaced the files in DVDsp. One thing with dvdsp is the audio files are huge aifs compared to the ac3s you can make with compressor.

[Shane Ross] “HDV is 4:2:0…”
True, I somehow missed that he was working with HDV.
Also, keep in mind that encoding in DVDSP will not yield great DVDs from HD sources. There is some type of distortion that takes place that often creates a wave-like effect in the picture.
