Infoseite // "Dropped frames rate of about 1% of" normal "?



Frage von iotatau:


Hello,
my first film camera was four years a JVC GR-DV3000 EC.
http://www.jvc-victor.co.jp/english/accessory/video/dvc/gr_dv3000.html
(Seems a real vintage car to be in the forum, I have no input into the camera found.) Basically I like movies, but I come from a lack of time some of them. Overall, I have in the four years up until 15 hours. The "capture" I currently collected with Magix Video Deluxe 2007 on a notebook with a Pentium 4 1.8 GHz. Firewire connection, when transferring the virus scanner and LAN off. Unfortunately, after each video deluxe capture a more or less large number of "dropped frames" to between 100 and 2000 totaled approximately 100,000 frames per tape. In the name "Sony" has been trusting the majority of my Sony Premium tapes. A search here in the forum shows that the combination of JVC Camera / Sony Premium tapes is not recommended. Is my observed rate of dropped frames for Sony Premium tapes to be expected? Recommended that a cleaning cartridge? Are there special MiniDV tape recommendations for JVC? Specifically asked: Does anything about Panasonic AY-DVM63PQ?
Thanks in advance!
Jochen

After all, what I know: a clear no. The "problem" (if there is one) with the Sony tapes refers rather to pollution caused by abrasion band. The cassettes are normally only once no worse than others.

A clean head drum with a regular cartridge should be able, without dropped frames to work. For me (Pana GS180, Magix VdL 2007) then I just get dropped frames when I capture the next example, the Internet browser and start surfing the net. Otherwise: zero dropped frames, synonymous with a 80-minute tape.

Had quite possible. Is he with the PC and the firewire cable everything okay?

I do not otherwise fall disturbances s.dem PC. Save I leave on an external USB 2.0 hard drive, 500 GB, still pretty empty and unfragmented.

To do: I will be a protocol and lead me, for each reading, the drop-rate note. Then I can determine if a cleaning tape brings an improvement, whether the quality of an elite band deteriorates with time, as the drop rate for different tape types is. At the gathering of such experience as a camcorder, I had not thought beginners.

Too often it is in fact not been mentioned, but there's already a handful of contributions such as these:

Well, I was in the "Advanced Search" with "JVC 3000" search option "After all the words." Result: "No articles meet your criteria." Synonymous now - so thank you for the list of four contributions.

That is strange, because when I get this information 52 result, but not everyone with this camera to do. On occasion, I can but you still like a few links for it.

Hello Jochen,

External hard disks can (but need not) when capturing problems. How it looks when you get to an internal hard disks captures?

On paper USB 2.0 is yes for 400 Mbit / s, well, well over the speed of your camcorder. However, systematic errors must be addressed, and so I tried the first variant this proposal - on the internal hard drive disk. This is when my notebook is not the quickest, but try it out. And lo and behold - bingo! The same MiniDV tape once external USB-2.0-plate captured - 1000 "dropped frames". Internal: 0 (NULL) "dropped frames"! Sensational. Rarely is a mistake as soon as clearly circumscribed.

Meanwhile I had already signed a 10-pack JVC JVC tapes and a cleaning tape ordered. The cleaning tape I need for happiness is not only once ... Now is the 1% drop rate for the 15 bands carry a nuisance. I guess I invest an additional CPU-working day, they cleanly on the calculator to get.

Once again, thank you!

There are, theoretically even 480 Mbit / s for high-speed USB, but the practice ... see Hichspeed USB is [not] faster than Firewire-400.

It would be tantamount to an attempt to outline the USB disk times s.einen different USB port to jam or to a firewire hard drive to capture.

I have currently not much variation possible. My only calculator with Firewire offers only a USB 2.0 port. It is a notebook vintage 2002, which originally had only USB 1.1. USB 2.0 equipped me with a PC Card after. As mentioned, the drop rate of capture to the internal plate has significantly improved. My 15 MiniDV tapes I have read all again, here the result: [code: 1:9 f799522c8]
# Drops tape
01 0 0.0% Panasonic DVC Linear Plus
02 360 0.4% Panasonic DVC Linear Plus
03 64 0.1% Sony Premium
04 0 0.0% Sony Premium
05 320 0.3% Sony Premium
06 0 0.0% Sony Premium
07 2 0.0% Sony Premium
08 273 0.3% Sony Premium
09 149 0.2% Sony Premium
10 0 0.0% Sony Premium
11 257 0.3% Sony Premium
12 29 0.0% Sony Premium
13 0 0.0% Panasonic DVC Linear Plus
14 164 0.2% Sony Premium
15 58 0.1% Sony Premium [/ code: 1:9 f799522c8]
An interesting observation was a tape at 15: There is equal to the beginning of a weak spot where the dropouts reproducibly only as crackle. That in my opinion a weakness of the Calculator Hardware. The principle possible flawless reading of all bands include a strong contamination from the camcorder. So just stay weak band positions as a cause.

Next steps: a packet with JVC tapes and a cleaning cartridge is underway. Upon receipt, I will focus once again the vulnerability out, perform a head cleaning and then directly back out the problem area. Also I would like to order more for my calculator a firewire card so that I have to capture him synonymous use.

These exercises are primarily a preparation for the next camcorder. I liebäugele with a Canon HV20, which is synonymous MiniDV uses. Any loss of quality through tape problems, I would like as well as possible under control.

Antwort von Markus:

Volume overstretched agencies could also be a cause for frames to be dropped. Overstretched, a tape often then, if the tape is ejected and re-inserted. Many users do not know that this will only end s.Bandanfang or should happen, so the recordings between prejudice remain.

Furthermore, we have s.Bandanfang at least 30 seconds forward (better 60 s) before the first "wanted" pictures takes place. In this area, the error number of a Videorbandes particularly high. The same is true for the end of the tape.

For short breaks in the recording tape to be partially synonymous dropped frames counted. Furthermore, the repeated reuse (Delete, Neubespielen) of MiniDV tapes at some point to such problems.

Your listing shows so synonymous that tapes the same type (and probably partly synonymous Carg same) is not the same number of dropped frames deliver. This includes the tape as a reason for this largely.

Very interesting and immediately obvious tip, thanks. Is there a book in which such advice can be found?

Meanwhile, the cleaning tape arrived, the next test is nothing in your way.

However, there are new sites. Two of them:
- Today met a Glidecam 2000. Am I still fine-tuning must tinker with the camera seems to be too easy, I must conceive me complaining.
- The first DVD from the fresh Capture burned. From another forum post I took the recommendation of a bitrate of 7.3 megabits / s. Ärgerlicherweise had a new DVD player (Elta 8847) when playing problems (freezing of the picture for several seconds). No problems with another player, Philips DVD729, and is not synonymous with various PC software players.

My Knecht-PC computing needs per-hour DVD 4.5 h CPU time for encoding (highest grade 15 for MainConcept codec for video deluxe), so it is with the 15 tapes one weeks busy.
