adelaideviewer Posted October 24, 2004 Posted October 24, 2004 Hi all, Just a query - when I get my Toppy recording to the point of burning onto a DVD, is the software compressing this to put it on the DVD or can you leave it as is, subject of course to available DVD disk space (4.7 gig). If I use a dual layer disk on my LiteOn Burner can I then get a reasonable amount of SD digital or even the HD stream from the Toppy onto a DVD disk. Can anyone give some specificatons on amount of recording time that will go onto the DVD and what are the quality characteristics compared to the original Topfield rec files. Sorry to be so long winded! just another curious and enjoying the Topfield new user!

If I use a dual layer disk on my LiteOn Burner can I then get a reasonable amount of SD digital or even the HD stream from the Toppy onto a DVD disk. <{POST_SNAPBACK}> Because our SD streams are at a fairly high bitrate, you will find most films will be more than a single 4.7GB disk and you'll need to shrink using something like DVDshrink (free). The quality is superb in general and even the heavily squashed ones are still fine on my TV (which is pretty good). If you have dual layer then I've seen nothing that wouldn't fit, but given the cost of dual layer balnks I'd be tempted to buy the real movie since you get surround sound which you don't get on SD, and no ads all over your film. I sometime cut large movies into 2 parts to avoid compressing too much. I think Fossil has done some HD to DVD messing and is pleased with the results. B

Yep, assuming you can fit the file in the disk space, you can burn the picture identically as broadcast. From memory, the bitrate tends to be ~6.5Mbit/sec but varies from channel to channel.
tonymy01 Posted October 25, 2004 Posted October 25, 2004 I have found that most approx 2 hour movies will fit on a 4.7G DVD without shrinking, and thus the quality is identical to what was broadcast (well, if you don't re-encode with Nero etc. This is using the techniques I mention on my site, i.e. projectX, TMPGenc DVD Author, burn). Of course, the movies need to get the ads removed to fit, so if they were ABC movies, you would probably need to shrink them. So as a guess, about 1hour 30mins is about what will fit without re-encoding, and this ads up correctly when doing the calc for how many minutes of 7megabit/s video that can fit into 4.7G. Regards
Donald Posted October 25, 2004 Posted October 25, 2004 As an example, I was recording Angel earlier this year and once I removed the ads, I still had to compress a little bit (using DVD Shrink at about 90%) to fit 2 episodes onto a DVD, probably about 90 minutes all up. Note that Angel was on Prime, which has the highest bit rate (about 8Mbps). I think SBS is the lowest and you might get more than 2 hours without compressing. I noticed the small drop in picture quality but my (analog) friends thought it was perfect.
tonymy01 Posted October 25, 2004 Posted October 25, 2004 Jeepers! My 2 eps of Angel per DVD, including a funky animated menu I created was only about 3.8G! This is Seven in Sydney. All adverts were of course removed. Now I have bought the box sets on their $20 specials, I have the whole lot thanks to 7 digital. Regards
adelaideviewer Posted October 25, 2004 Author Posted October 25, 2004 Hi Tony and others, Thanks for all your detailed replies. I was trying out NERO express for the first time yesterday. Tony, are you suggesting that Nero does some sort of compressing? Or is this something that you set in its preferences. Thanks
tonymy01 Posted October 25, 2004 Posted October 25, 2004 I haven't tried Nero Express, but Fossil has. If the building DVD part of the creation with Nero express, for approx a 90min recording says it is going to take about an hour, then it would definitely be re-building the MPEG streams (recompressing too), but if it is quick like TMPGenc DVD Author, then it may just be taking the streams without changing them, I really don't know (I did try a nero product a while ago, and it was a complete decompress & recompress type solution, hogging tonnes of CPU cycles and taking ages, all to the detriment of the already 99% DVD compliant streams that DVB sends). Regards
ToeCutter Posted October 25, 2004 Posted October 25, 2004 I was wondering the same thing about Nero. I encoded a DVD last night and it took over 2 hours to prepare 2 episodes of Survivor for DVD. An earlier version I used simply involved burning the .vob files and no preparation was necessary.
fossil1503559605 Posted October 25, 2004 Posted October 25, 2004 Hi ...I have been absent getting my laptop back to full operation with all programs running smoothly after reformatting... With Nero 6, it needs to be Nero 6 Vision express..Below is some info I have just posted in the other forum...as far as doing HD goes, the result is great but far too fiddly and time consuming...like 2.5- 3 hours against 35 mins for a 1 hour file of a .rec dropped directly to Nero Vision Express. other forum Eka...if you have Nero 6 vision Express and Elecards Moonlight Player loaded, you can drop .rec files direct into Nero 6 without demuxing....If you want to edit it you can do that direct in Nero, or easier in Wombles MPEG Video Wizard and the file will be as you think it should be as far as resolution and size and pal type which are all selectable...I have done many disks of many programs, and if you don't mind ads, and you get the correct codecs loaded,(these are generally loaded when the Moonlight player is installed...) then demuxing is not needed, otherwise I find the best editors is Wombles...it will let you edit .rec files without demuxing and outputs the file without recoding...it is renamed as MPG...Wombles MPEG Video Wizard also makes a great player and needs no codecs...it plays as is without extra codecs...and is extremely quick with no rendering lag... The end results with SD are fantastic. EDIT Oh....I forgot to mention....the times not counting transfer from the Toppy to the PC...(I am probably using a different method than you) are.... from dropping the file direct to Nero and finishing burning a 1 hour file is about 35-40 minutes..... allowing for transcoding from the .rec file a format Nero can burn to finishing burning. This makes it very tempting to not do the editing process which takes about five minutes and another 5 minutes to output it....so ...If I want a clean file that has better quality than a bought DVD I will edit it...if not, I burn it with ads and the same good quality...although some of the saved time by dropping straight to Nero is negated by editing out 20 mins of ads...for example, in the program called The Practice, it only contains 35 minutes of program...Stargate always contains about 40 minutes as an example. Tonight I have edited 4 separate hour programs and have written them to disk editing and burning concurrently and the whole process for four hours including editing and burning took less 2.5 hours Total....I could have placed two on each disk, but with disks only costing 68 cents, I burnt separately, because the programs were different...Australian recently produced HD programs process better than American HD programs for some reason...but really, for the 10% improvement if that, it just not worth processing HD Ask away and I will answer what I can. foss
