Hvordan lage film av sonardata

Jeg vil advare leseren om at dette innlegget inneholder ekkolodd-nerde-opplysninger som når stadig nye høyder... :)

At jeg tar opp sonarlogger fra ekkoloddet er ikke noe nytt, jeg bruker disse for å lage dybdekartene mine siden de inneholder informasjon om posisjon og dybde. Men DETTE innlegget på en svensk blogg om vertikalfiske ga meg en ide om å lage film av sonarloggen. På bloggen sin har Joakim laget en video hvor han har ett kamera rettet mot ekkoloddet, og ett mot seg selv. Poenget er at den som ser på filmen skal se det samme som ham, altså jiggen, fisken og selve hogget. Nå er Joakim proff på både vertikalfiske og film, så resultatet ble riktig bra. (Fisk får han også.) Det skal bli spennende å se hva han får festet på film fremover.

Tanken min var at siden sonarloggen kan sees hjemme på en PC med Lowrance sin Sonarviewer, var nerdeiden å lage film av denne. Så nå har jeg testet et gratisprogram som heter Any Video Recorder. Dette programmet tar opp det du har oppe på PC-skjermen din, og lager en filmfil i mpeg4-format. Denne kan så lastes opp på YouTube eller andre steder man vil legge ut film. Under ser du resultatet på YouTube.


Sonarviewer


Dette er en treminutters snutt fra Steinsfjorden, og viser det vanlige 2D ekkoloddet til venstre med 50 kHz og DownScan med LSS-1-giveren til høyre. (Jeg husker ikke om jeg kjørte med 455 eller 800 kHz på den) Her ser du både stimer med agnfisk, og enkelte større ekko.

Fordelen med Any Video Recorder (bortsett fra at den er gratis) er at den er veldig enkel å bruke. Du legger bare en rute over det du vil ta opp, ruten kan dras og tilpasses skjermformatet du skal ta opp, og så trykker du start. Du har også en mulighet til å velge automatisk stopp av opptaket etter et antall minutter du bestemmer selv. Når programmet er ferdig, lager det mpeg4-filen, og lagrer den der du vil med det navnet du vil på filen.

Så får vi se om jeg kan få festet dyprigghugg eller vertikalfiskehugg på film etterhvert.

What is the difference between Lowrance HDS and Lowrance Elite HDI

Ever since the Elite 7 HDI came on the market I have recived a lot of questions regarding the difference between the HDS-range and Elite HDI. In this article I will try to list most of the differences, seen from a keen anglers point of view. This also means looking at most of what Lowrance has to offer, but I'm sticking to models sold today and models I personally would recommend. The three main model-series, plus the newcomer Elite CHIRP. HDS Gen 2 , true multi function displays (MFD) with button-operation and screensize from 5" to 10,4". HDS Gen 2 Touch , true multi function displays (MFD) with touchscreens and screensize from 7" to 12". Elite HDI , "stand alone", ie not ment for networking besides VHF and AIS. Button-operation and screensize from 4,3" to 7". Elite CHIRP , as Elite HDI but with CHIRP-sonar and faster processor in adition. Screensize 5" and 7".   HDS Gen 2 Units from this series are seen while fishing

What is the difference between HDS Carbon and HDS Live?

Here we go again, a new generation of the Lowrance HDS. And with that Facebook and the different forums are flooded with questions referring to the difference between the new and the old. So what is the difference between Lowrance HDS Live and HDS Carbon?

What is the difference between HDS Gen 3 and HDS Carbon?

Whenever a completely new model or a rewamp of an existing model comes out, we get the same question: "What is the difference?" Lowrance HDS Carbon Previously I have written a few articles about the differences between some of the (now historic) Lowrance-models: What is the difference between Lowrance HDS and Lowrance Elite HDI? What is the difference between Lowrance HDS Gen 2 and HDS Gen 3? This time we will take a look at the difference between Lowrance HDS Gen 3 and the brand new Lowrance HDS Carbon that was released 15. december 2016. We will look at the technical stuff, and try to translate that into what it will mean when out on the water. Lowrance HDS Gen 3 HDS Carbon is actually the fifth version of the popular HDS-series. Before it came HDS Gen 1, HDS Gen 2, HDS Gen 2 Touch and HDS Gen 3. HDS Gen 2 Touch marked a new area of how Lowrance run their model-updates, since it was released shortly after HDS Gen 2 and the two lived alon

What is the difference between Lowrance HDS Gen 2 and HDS Gen 3?

The cyclus in which models change have become shorter and shorter. Is there any real difference between them anymore? When I started out in this game most people would say that their sonar should stay onboard for 8-10 years before they would even consider upgrading it. Everything with less then 5 years on it was considered "new". But as with all things containing a circuit-board, development has been ever accelerating and we are now down to a two or three year cycle between model-changes. I belive that this is to the consumers advantage, but is "the new" always better then "the old"? In most cases the answer to that question is "yes", but it`s up to you to decide if that difference is big enough for you to spend your hard earned cash. Technically it is easy to spot the differences, but whether you will notice it out on the water is a more subjective mather. In this article I will try to look behind the marketing, and point to the actual diff

What is the difference between Lowrance HDS Live and Elite Ti2?

Lowrance as a brand of marine electronis is well known to all anglers, but the differences within their range of different models seem to cause quite a few questions out there. Here we will try to outline the difference between Lowrance HDS Live (top end) and Lowrance Elite Ti2 (middle range). Lowrance Elite Ti2 vs Lowrance HDS Live (photo; lowrance.com) As usual, we will start with the tech and then try to translate those technical aspects to practical differences while out on the water. Hardware - housing, screen and connections. The screen and housing on Elite Ti2 is the same as on the previous Elite Ti, and again more or less the same as on HDS Gen 2 Touch. (The memorycard-door and mounting-bracket is different from HDS Gen 2 Touch.) This is by no means new stuff, and compared to the more advanced housing and screen on HDS Live, Elite Ti2 is starting to show its relative age. However, with that in mind it is worth noting that when looking at the competition, several of
