I have an hour and a half sequence in DNxHD 145; I mixed it down to able to send quick time ref to Serenson; in Sorenson I used DVD NTSC Large preset; the only thing I changed was 4:3 to 16:9 for pixel aspect ratio cause it was HDV as its source and dropped the max bit rate to 7000 kbs, and I used Bottom Field First for Field Encoding.

After around 6 hours of Sorenson magic I moved my .m2a and .m2v to encore and I authored it for DVD NTSC (bottom field first by default).

At the end when I play my final DVD I can see edges especially when there is a lot of movement. I only have a few more hours to adjust the settings, go through a few hours of Sorenson work and make another copy since I need to send it to a festival by the end of the day.

Any suggestions please,

Thanks

Fast and dirty try downloading a program called ReStream. It will let you reset the field order in your encoded video. IFoEdit may also give you this option

For future work without the current time pressures here is a post I saved showing options in Sorenson to preview and get your settings right before you do the main render.

"Squeeze Preview mode The biggest complaint that I had when searching for the "exact right" compression settings is the time that it took to encode a file, over and over again, once I had modified the settings or tried a new codec. Well, this headache can be virtually eliminated with the Compression Preview Tool in Squeeze. This relatively obscure tool is found directly under the beginning of the timeline in the preview window.

To create a compression preview I must first import a file, apply an audience preset and make any changes in the preset as needed. Next, I need to place the play head in the timeline of the file where I would like to see the preview. Using the pull down arrow on the right I can choose a specific time period between one and five seconds that I would like to encode. Once the time is chosen Squeeze shows me the time of the video that it will encode.

Lastly, I just click the play icon next to the drop down and Squeeze creates the preview and launches it in my default player. This tool is particularly useful when I'm choosing the best codec or data rate to use, and especially when I'm working with long form video. The preview gives me a good idea how my final compressed output will look, without taking the time to encode the entire video. This way I can add filters, change data rates, switch codec and tweak the settings to my hearts content until I am completely satisfied with the look of my video."

HD is upper field first, SD (NTSC) is lower field first.

Thanks guys,

The little play/preview button in Sorenson is great, had no idea about it BTW.  But I am a bit skeptical cause our computer monitors are progressive, as far as I know, and our TVs are interlaced so previewing will help but the final check I think should still be on an interlaced TV.

Also I do realize that HD is top field and SD is bottom first field and that is the core of the problem I have. Now I have another week for a better DVD copy of my project and I want to make really nice...

At least in my experience SD DVD is still required a lot more than Blue-Ray even though source footage is more and more in HD than in SD. So the question is, at what point do I need to switch the fields cause my timeline settings are in 60i and DVD is SD for the best results, considering there is more time to spare/play now.

I tried many options today, certainly not all of them. In general I was just under impression that HD footage could produce way better results when the final product is delivered in SD DVD. I just haven't done a project like this for a while and now I need to figure out the settings again. But I remember that I was able to produce great results from HDV material to SD DVD before. And there were a few posts in that regard but can't find them.

Thanks a lot,

Descriptively name (NTSC DNxHD145 to SD NTSC DVD)save the template when you get the field order and quality to your satisfaction

Hey Bro, have you found a solution to this? I am having the exact same problem. I've tried various field orders and bit rates in Sorreson, all giving me good m2v results, but once burned im getting the interlacy strobe, flicker. Looks terrible.

Thanks,

Andrew

Sorenson does not (unless I am more blind than I think) let you select what the source field order is. Then it seems to me if it gets the source field order wrong no amount of changing the output field order will solve the problem. At that point I quit Sorenson and use ProCoder or TMPGenc that will allow me more control.

Thanks for the reply.

I always found it strange that Sorenson doesn't allow you to set the source field order, cause how does it know? HD is upper, SD is lower, so it has a good chance of getting it wrong. Guess I'll have to try something else.
