Default Downloadable Edius HD down conversion to DVD MPEG2 test project.

Hi All.

Here is a test project that contains DVD MPEG2 compatible encodes, using various methods for the down conversion process.

The test file is a short Edius EX3 1080P 25fps video clip. Although this camera and clip may not be the highest resolution possible for such a test, there is enough fine detail in the footage to show the differences in the down conversion methods.

The final encodes to DVD MPEG2 compatible files was chosen as this is the usual format used to show SD footage. CBR 8Mbit was chosen to level the playing field for final outputs, and is a there about bitrate that most encoders would need to show off their highest visual output for DVD work.

Hopefully this will help to show some of the various methods of down conversion for Edius 1080P projects. Please feel to use the source clip for your own down conversion tests, and to post your results for other Edius users.

There are two sequences in the project. 1:1 is all MPEG2 clips on top of each other so you can mute the tracks for A/B comparison. And Zoom is the same thing but with high zoom ins.

Special thanks to Dave Evans, NakedEye of www.nakedeyedv.com for supplying the TMPEG Authoring Works 5 (T5) encodes and his workflow description.




Here are the descriptions of Dave's T5 encodes.

DC Component Precision = 10bit
Test 3
Import to T5 and choose Progressive, all other settings to match source footage.

Filter = Picture Resize. Settings = Full Screen. Keep Aspect = Unchecked. Interlaced with High Quality Resize = Unchecked.

Encoder Settings = MPEG-2 Video.
Standard Encoder.
MP@ML.

Here are the descriptions of the other encodes.

EDIUS 5-51 DOWN SCALED SD HQ TO EDIUS 5-51 MPEG.m2v

This is the EX3 clip exported from an Edius 5.51 HD timeline to a master HQ SD file, then re-exported to an 8Mbit CBR MPEG2 DVD compatible file at best encode setting with 5.51.

EDIUS 6-02 DOWN SCALED SD HQ TO EDIUS6-02 MPEG.m2v

This is the EX3 clip exported from an Edius 6.02 HD timeline to a master HQ SD file, then re-exported to an 8Mbit CBR MPEG2 DVD compatible file at best encode setting with 6.02.

Here is the Edius 5 project/session data.

Here is the master Edius EX3 clip, it's from the X264 test.

Hi Red Union Films

I don't know whether I should post my problem here or not.But once again I need your help.
I am going to shoot a wedding ceremony in HDV format with my Sony FX 7 And Sony V1 P.It would be 1440*1080 50i.
My querries are
1.What option should I choose for smooth editing ? Canopus HQ or MPEGTS?
2.How is it done with Procoder 3 to export into MP4 (H.264) with aspect ratio maintaining as 16:9 ? I did some export but came out with squeezed image as 4:3. A step by step procedure please.
3.What is this COLOR SPACE about exporting HD/HDV to SD DVD or MPEG 2 ?
Still confused about why need color correction when exporting from HD to SD/ DVD ?
4.Where in the Procoder 3 COLOR SPACE Settings are?And How is it done?
A step by step procedure is highly appriciated.
Thank you.

Regards
Pabitra Kasaa

Hi Pabitra.

This test project was to show the differences in the ways that you can go SD MPEG2 DVD. It may give you some help to create your DVDs.

Anyway, will try to help with your questions.

1.What option should I choose for smooth editing ? Canopus HQ or MPEGTS?

Although Edius is well capable of handling many different types of transport streams natively, such as HDV. I would always use either HQ or HQX for my tape ingests. You only need HQ for HDV. I use the highest quality for this codec, although many people believe that fine or super fine is well good enough for HDV. Edius will do more things easier, faster, and more of it using HQ, as it is optimised for Edius and is an Intra frame codec.

2.How is it done with Procoder 3 to export into MP4 (H.264) with aspect ratio maintaining as 16:9 ? I did some export but came out with squeezed image as 4:3. A step by step procedure please.

You may be getting mistaken for Anamorphic squeezing, which will look like 4:3 if not recognised by whatever is playing it back. You could do with doing a Google on the word anamorphic and learning what it does. I use X264 for H264/MP4, but you may want to try out Edius 606 for this, as it is much easier and is the best H264 so far from Edius. May even be better than PC3.

3.What is this COLOR SPACE about exporting HD/HDV to SD DVD or MPEG 2 ?
Still confused about why need color correction when exporting from HD to SD/ DVD ?

Don't worry about colour space, the encoder will do all the work, again try Edius 606.

4.Where in the Procoder 3 COLOR SPACE Settings are?And How is it done?

Been a while since I used my PC3, again try Edius 606, it's easier, quicker workflow, and possibly better.


Cheers.

dave.

When asking questions about type of codec and which would be better to use, it helps us help you if you put your system specs in your signature. Just a friendly suggestion.

Hi Jerry.

Pabitra was being very specific about the choice between two codecs. In my experience the HQ codec is the least demanding regardless of system spec, when compared to other available codecs at the same resolution and size.

As you know, an intra frame codec is easier to deal with than an inter frame one.

Cheers.

Dave.
